Hi all,

I have been brewing for about 1 1/2 years now, with 20 batches under my belt. I finally made the jump to all-grain for my last 2 batches (can’t believe that I waited so long). Not bragging, but I did knock out some really nice beers with extract which I would like to brew again, this time all-grain.

My question is how would I cross over a recipe? For instance, here are the fermentables I used for a nice IPA I made a couple of months ago;

9.0 lbs. LME (Syrup)
.50 lbs. CaraMunich II
.50 lbs. Crystal 40
.50 lbs. Crystal 120
.25 lbs. Special B

The grains went in for a 30 minute steep. How would I convert this to an all-grain recipe? Thanks in advance for any suggestions and advice!

ALL-GRAIN TO EXTRACT
Amount of pale malt x .8125 = amount of liquid malt extract
(example: 8 lbs. pale malt x .8125 = 6.5 lbs. liquid malt extract)
Amount of pale malt x .6875 - amount of dry malt extract (DME)
(example: 8 lbs. pale malt x .6875 = 5.5 lbs. dry malt extract)
Amount of wheat malt x .937 = amount of liquid wheat malt extract
(example: 6.5 lbs. wheat malt x .937 = 6.1 lbs. liquid malt extract)

EXTRACT TO ALL-GRAIN
Amount of liquid malt extract x 1.23 - amount of pale malt
(example: 6.6 lbs. liquid malt extract x 1.23 = 8.1 lbs. pale malt)
Amount of dry malt extract x 1.45 - amount of pale malt
(example: 5 lbs. dry malt extract x 1.45 = 7.25 lbs. pale malt)
Amount of liquid wheat extract x 1.07 - amount of wheat malt
(example: 6.6 lbs. wheat extract x 1.07 = 7 lbs. wheat malt)

Thanks for that!!!

That seems to be good for the base malts, but will I use the same amounts for my specialty grains? Or do I need to change the amounts because of a 30 minute steep versus a 60 minute mash? Thanks!

Specialty grains stay the same. Welcome to the dark side. There is a good article in the http://www.brewboard.com/index.php?showtopic=35208 for AG brewing.

Thanks!!!!

Man, the dark side rules. Like I said in the beginning, I can't believe that I waited so long to jump in. At first it seemed scary, but once you go there, it's not that big of a deal. Calculate your strike, maintain temp, sparge, boil. Easy peezy. lemon squeezy. I know I still have a lot to learn, but the basics are there. This is getting fun and addictive!

I've always used Ken Schwartz numbers to convert.

Grain to LME multiply by .75
Grain to DME multiply by .67
LME to grain divide by .75
DME to grain divide by .67

LME to DME multiply by .89
